I purchase this clock as a replacement for a older Timex travel alarm clock that I lose . while this model function on a basic level , it be disappointing overall . as another reviewer mention , this clock gain time quickly . after just a couple of day it will be minute ahead of the actual time . if you only use the clock for weekend trip this probably will not be much of a inconvenience , but for longer trip or regular use at home , this be a bit of a nuisance . I can honestly say that in my entire life I have never have any clock , watch , or other appliance so poor at keep the correct time . I have also be disappoint with the quality of the Indiglo backlight on this clock . on my last travel alarm , as well as my Indiglo watch , the Indiglo backlight be bright and make the character easy to read in the dark . however , on this clock the Indiglo backlight be feeble by comparison . it be just bright enough to qualify as usable , but if you eyesight be not great the combination of the weak backlight and the fact that you probably be not wear contact or glass in the middle of the night may make this clock difficult for you to read . as far as the user interface be concern , the time display be very large , but other on-screen item , such as the `` alarm on '' indicator , be not necessarily obvious by a quick glance at the display . the Indiglo button , as you can see in the picture , be in the middle of the face of the unit . my last travel alarm place this button on the top of the unit . if you can imagine try to illuminate you clock in a pitch dark room , you can probably guess which location be more convenient . fortunately , all the button you need to set the clock be easily located on the lower half of the face of the unit . for set the time\/alarm the clock have a pair of up\/down button that move the time in one -lrb- if you press and release -rrb- or 15 -lrb- if you hold -rrb- minute increment . this be particularly useful for make small time adjustment backwards . overall I have be very disappoint with this clock . it lack some of the ease-of-use feature I be use to , and it suffer from poor craftsmanship . it be relatively inexpensive and it have not technically break , but if I could go back in time I would most certainly purchase a different travel alarm .
